Abstract
A waveform of a desired sound is displayed on a CRT, and is observed for the analysis of the waveform. Waveform information including a shape, a repetition number, an amplitude, and a frequency of a segmental waveform which is a part of the displayed waveform is supplied to a repetitive PCM data generating unit, by which the repetitive PCM data are generated. The repetitive PCM data are developed to be a PCM sound signal which is converted to an analog output sound signal. A sound generated by the analog output sound signal is appreciated.
Claims5
A system for developing sounds, comprising:
- displaying means for displaying a waveform of a sound signal;
- first generating means for receiving from said displaying means waveform information obtained from visual analysis of said waveform displayed on said displaying means, said waveform information including a shape, a repetition number, an amplitude, and a frequency of a segmental waveform which is a pair of the waveform displayed on said displaying means, said first generating means generating repetitive PCM data in response to said waveform information;
- and
- second generating means for receiving said repetitive PCM data from said first generating means and generating a sound in response to said repetitive PCM data.
